os-clovy: Skill for Claude Code

.agents/skills/os-accounts-integration/SKILL.md

os-accounts-integration is a skill for Claude Code, Codex from open-software-network/os-clovy. It costs 156 tokens per session (3,883 once invoked), scanned A, original, MIT.

A guide for connecting apps and backend services to OS Accounts, Open Software’s shared login and credit-billing system. It covers user login, backend identity checks, and usage metering.

In plain words
What is it for?
Use it when adding Login with Open Software, handling PKCE login callbacks, checking users through a backend, or charging and topping up credits. It includes examples for Next.js, Hono, Fastify, Express, and Rust.
Why use it?
It removes the need to design these login, token-verification, and credit-payment flows from scratch. It also helps keep access tokens and paid actions handled safely.

This is open-software-network/os-clovy's own configuration. It tells Claude Code and Codex how to work on os-clovy itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything os-clovy configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

os-accounts-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OS Accounts integration

OS Accounts is the Open Software network's identity + billing platform: one login and one credit wallet shared across every app. Your app depends on OS Accounts (the arrow points app → accounts, never the reverse). It is the source of truth for who the user is and how many credits they have. Your job as a consumer is small and well-defined: federate login, verify the user on your backend, and meter usage.

This skill teaches the HTTP contract (works from any stack) and gives proven Next.js (App Router) consumer code plus backend auth-middleware (Hono, Fastify, Express, Rust). Read this file, then open the reference that matches the task:

Route the request first

If the user asks for... Open first Non-negotiable answer

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
